Sažetak
Soil samples from the industrial area in the town of Bužim, Bosnia and Herzegovina were analysed in order to determine their different manganese species. Samples were extracted from seven locations - at the manganese mine and the surrounding area. The paper aims to present the use of the sequential extraction method in determination of the specific distribution of Mn in soil, as well as in estimation of its origin, mobility and bioavailability in the sampling locations. Sequential extraction used here included determination of the amount of Mn in various soil fractions: the water-soluble fraction, exchangeable fraction, carbonate fraction, easily reduced fraction and the organic fraction. Additionally, it included manganese oxides or moderately reduced oxides, amorphous iron oxide, crystalline iron oxide and the residual fraction. It was determined that chemical properties of soil considerably affect the distribution of heavy metals within different soil fractions. The highest percentage of natural Mn was determined in the residual fraction (27.00%) at Popović polje, while the highest percentage of anthropogenic origin Mn was determined at Bućevci (57.00%) in the Fe-Mn oxides fraction. The highest near-total content of Mn was determined at Popović polje (20950.00 mg/kg). The highest percentage of natural Mn (27.00%) was determined in the same area. The highest percentage of Mn of an anthropogenic origin (57.00%) was determined at Bućevci.
